How to configure a high availability fieldbus on the basis of PROFINET
Introduction
The following section describes how to create and connect a high availability fieldbus on the
basis of PROFINET.
● Configure the components in HW Config.
● In the Topology Editor, configure the connections between the components in accordance
with the cable sequence in the system.
Requirements
● The PCS 7 project with a SIMATIC H station is open in SIMATIC Manager.
● HW Config is open.
● The redundant backplane is inserted in HW Config.
● In HW Config, each rack has been fitted with an 4xx-xH PN/DP H CPU and the required
synchronization modules.
● The PROFINET IO systems are added to the H-CPU. This can be done using Insert on the
H‑CPU.
Configuring in HW Config
1. In the hardware catalog, open the PROFINET IO > I/O > folder of the IO device type:
– ET 200M
– ET 200SP
– ET 200SP HA
2. Select the version of the interface module (ET 200M: IM 153-4 ...; ET 200SP HA: IM 155-6-
PN/HA) you are using and move it onto the PROFINET IO system using drag-and-drop.
